mastinosoft

It will be very nice if you have any ideas about this problem.

Please try this patch: https://codereview.qt-project.org/#change,85414

Just try to change content in lines 772-775 and 895 and try to rebuild and check this error again. Because I can not able to reproduce this error on my side.

mastinosoft

thank you I'll try it tomorrow when I'll back to my job. Hope it will works.

Hi tried to get to the code for Serial Port but it very complicated. Have to do a lot of registration and because I started with Linux just last month it will take more time that I have. Project have to be ready yesterday so I'm in trouble. If it possible can I found the famous SerialPort source code on the other way. You put changed *.cpp file but without all others file I can't do much with it.

download and install Git
enter command to download sources:
@git clone git://gitorious.org/qt/qtserialport.git@
enter command to change directory:
@cd qtserialport@
enter command to fetch a patch:
@git fetch https://codereview.qt-project.org/p/qt/qtserialport refs/changes/14/85414/2 && git checkout FETCH_HEAD@
Run QtCreator and open
@qtserialport/qtserialport.pro@
file in root directory
From the QtCreator, select your Kit with your desired Qt version (5.2) and re-build library
Open the console and go-to to the "shadow" build directory of the QtCreator
enter command:
@sudo make install@
re-run your application and check again

mastinosoft

Thank you, I'll try right now.

mastinosoft

had some problem with git but now is OK

mastinosoft

Now project opens but I have message:
@Executable /home/***/Documents/qtserialport/build-qtserialport-Desktop_Qt_5_2_1_GCC_64bit-Debug/examples/serialport/blockingmaster/blockingmaster does not exist.@
I have correct Kit information. "Shadow" build directory I spouse is "//build-qtserialport-Desktop_Qt_5_2_1_GCC_64bit-Debug" ?

kuzulis

bq. “Shadow” build directory I spouse is “//build-qtserialport-Desktop_Qt_5_2_1_GCC_64bit-Debug” ?

Yes. Now you should to run "sudo make install" to install QtSerialPort into your Qt 5.2 place (you can check it, see new qserialport*.so in your Qt 5.2 directory).

bq. Now project opens but I have message:

By default, the "make" command build only the library, without the examples.

To build examples you should to enter "make all", or, is more simple - try to open blockingmaster.pro file from QtCreator and re-build an example and to run. :)

mastinosoft

Thank you. I tried "Terminal" from examples and it not gives error messages but just stop to receive data. Nothing like this happens if I read data from Linux terminal.

mastinosoft

Thank you for all your time. I really appreciate that. But it seams that QSerialPort have problems. I switched to QBluetooth and now I receive all data as it have to be.
Best regards.

kuzulis

Can you please repeat again but with the new :

@git fetch https://codereview.qt-project.org/p/qt/qtserialport refs/changes/14/85414/3 && git checkout FETCH_HEAD@

command?

kuzulis

Need to do change directory from "~/Documents/qtserialport"

~/Documents/qtserialport $ cd qtserialport

because you do pull into ~/Documents/qtserialport but not into ~/Documents

please try again :)

mastinosoft

hi again.
Now I tried the new one you sent me. But unfortunately I have the same result. No error messaged but data stops after a few seconds.

kuzulis

Ok. Many thanks for your time. Seems that the solution of this problem should be postponed until I won't get an Bluetooth dongle and so on.

mastinosoft

Thank you. If you need to know so use I "Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)" and Qstarz 818XT GPS on
"Linux Mint 14 Nadia". Have a nice weekend.
